If a storm surge of those levels were to make its way down Long Island Sound, LaGuardia Airport in New York could be put out of action. The airport is a domestic hub for Delta and has two runways, both of which jut out into the sound.

According to the air navigation specifications of LaGuardia Airport, Runway 4/22 starts at a height of 20.6 ft above sea level and drops to 11.5 ft. Runway 13/31, however, starts at a height of only 11.6 ft above sea level and falls to a height of just 6.7 ft.
